Jirai kei is a subculture and whilst there are specific styles and brands commonly associated with it, those styles aren't "jirai". Jirai stems from and primarily surrounds culture around mental illness, homelessness and self-destructive/explosive behaviour, which is why it translates to landmine.

I think it's also important to remember within the western community that a lot of it is directly related to the culture around mental health, suicide and self harm within Japan itself and not just as a whole.

The reason jirais are called jirai is due to explosive outbursts and outwardly/visibly being mentally ill. It's something that stemmed from a culture of ableism and a lack of understanding/care regarding mental health that is a lot more severe in Japan than I think a lot of people realise. It's a derogatory term.

The styles associated with people who would be considered jirai are a lot more varied than is often represented within the western community - understandably considering most don't have a way to see the evolution of the subculture in japan itself.

If you want to wear one of the styles associated with jirai such as girly kei, do it, but please stop trying to rebrand/"reform" jirai.

Yes, there are specific looks that kind of visually solidify you as a landmine within the subculture, however there is no set "jirai look/style".
